Re: [dev] [OT] c syntax tree dumping tool

Thats great. I should take a look asap.

In fact i wrote a generic abstract tree parser based on some basic parsing rules so it can parse Java 7, javascript and others, but obviously not as well as yours. Not supporting macros and others..

I think anselm was already interested on something like this. So we can probably take it to do a suckmore sloc or a c compiler based in radare2 assembler backend. Which would be far less bare than Java EE 7 or llvm
